SPECIFICATION forming part of Letters Patent No. 759,952, dated May 1'7,1904.

Application filed July 18, 1903.

To all whom it may concern:

Be it known that I, CHARLES A. ANDERSON, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a specification.

This invention relates to improvements in walking-cultivators in whichone drag-bar has a connection with the axle, permitting it to have ahorizontal swinging movement and a vertical movementindependent of theaxle, and the other drag-bar has only a horizontal swinging movementindependent of the axle, and the axle supported upon carrying-wheels.

In the accompanying drawings, Figure 1 is a plan View of my improvedcultivator. Fig. 2 is a side elevation. Fig. 3 shows the connection ofthe left-hand drag-bar with the axle. Fig. 4 shows the connection of theright-hand drag-bar with the axle.

The axle is formed of double bars 1, having their ends 2 turned forward.Caster-wheels 3 have their shank portion 4 connected with the axle bystaple-formed bolts 5, surrounding them, passing between the bars ofthe-axle,

the axle are connected the books 7, to which the team is connected.

The connection of the right-hand drag-bar 8 with the axle is shown atFig. 4, consisting of the staple-formed bar 9, held in connection withthe axle by the bolt 10. The free ends of this bar are perforated andreceive the perforated forward end of the drag-bar and are held togetherby the bolt 11. This connection allows the drag-bar to have a movementin a horizontal plane independent of the axle by which the drag-bar israised. The axle will be tipped forward on the caster-wheels.

The left-hand drag-bar 12 in its connection with the axle is shown atFig. 3. Said connection consists of the staple-formed bar 13, held inconnection with the axle by the bolt 14. The front end of the drag-bar12 has an exten- Serial No. 166,202. N mod l-J sion 15 pivoted thereto,and this extension has a vertical hole through which a bolt 16 passes,connecting it with the free ends of the plate 13.

The pivotal connection between this dragbar and its forward extensionpermits the dragbar to move in a vertical direction, and the pivotalconnection between the extension and the axle allows the drag-bar tomove in a horizontal direction. The movements of the left- -handdrag-bar are independent of the move ments of the right-hand drag-bar,the righthand drag-bar serving to hold the axle in an upright position.

The connection between the forward ends of the drag-bars and the axleare adjustable in the lengthwise direction of the axle to cultivate rowsof corn of different widths.

The left-hand drag-bar supports two shovels 17 and 18. Ahandle 19 hasone end connected to the drag-bar, and a brace 20 forms a connectionbetween the handle and drag-bar. To that portion of the dragbarsupporting the shovel 18 is pivoted a hand-lever 21, having a rearwardextension 22. A shoe 23 has a pivotal connection with, the drag-bar andextends rearward, and a link 24 connects this shoe with the extension 22of the hand-lever. A bracket 25, with projections, is secured to thehandle 19, and the hand-lever is capable of being moved into engagementwith the projections.

By moving the hand lever rearward the drag-bar will be raised into theposition shown in dotted lines, Fig. 2, and held by the projections ofthe bracket, thereby holding the shovels free of the ground fortransportation, and by adjusting the hand-lever into other spaces of thebracket the shovels can be held at other elevations for cultivating atvarious depths.

The construction of the right-hand dragbar and its hand and liftinglever connection are the same as the left-hand drag-bar, and likereferencenumerals are employed for both.

I claim as my invention- 1. In a cultivator, the combination of an axle,wheel-supports for the axle, and two drag-bars having a connection withthe axle,

one capable of a horizontal and Vertical movement independent of theaxle and the other capable of only a horizontal movement independent ofthe axle.

2. In a cultivator, the combination of an axle, wheel-supports for theaxle capable of bodily adjustment in the lengthwise direction of theaxle, and two diag-bars having a connection with the axle and capable ofbodily adjustment in the lengthwise direction of the axle, theadjustment of the wheels and dragbars being independent of each other.

3. In a cultivator, the combination of a drag-bar, a support for theforward end of the drag-bar, a shoe having a pivotal connection with theshovel-standard near the shovel,

and a hand-lever having a pivotal connection with the drag-bar and alink connection with the shoe.

4. In a cultivator, the combination of a drag-bar, a support for theforward end of the drag-bar, a shoe having a pivotal connection with theshovel-standard near the shovel, a hand-lever havinga pivotal connectionwith the drag-bar, and a link connection with the shoe, a handleconnected to the drag-bar, and a rack-bar supported by the handle withwhich the hand-lever engages.
